It took me a little while to find it but here is a recipe I got from Sharonll who is primal as well and used to blog here. I just made some last week and it is good. I left out the chicken livers and my smoker was not working but it was great anyway.
Let me know what you think if you try it as well. This is called Braunschweiger which is pretty much the same as liverwurst in my book.
